Background and aims: Cardiovascular disease is a major cause of mortality in end-stage renal disease patients (ESRD). The rate of elderly and poly-pathologic patients in ESRD is increasing. Elevated levels of C-reactive protein (CRP) have been shown to be associated with increased mortality in ESRD patients. The aim of this study was to examine whether, in elderly ESRD patients, the conventional relationship between elevated CRP and cardiovascular mortality is maintained. Methods: This prospective European cohort study included 150 ESRD patients. Data obtained at baseline included demographics, comorbidity, late referral to a nephrologist, high-sensitivity CRP, and serum albumin and hemoglobin levels. Cardiovascular events were analysed as a combined end-point. Results: The mean age of the cohort was 61 years (22-90), with 33.3% of patients over 70 years (75 yrs, 70-83 yrs). Forty-two patients (28.2%) experienced at least one cardiovascular event. Interaction between age over 70 years and CRP exceeding 3 mg/L was a protective factor. Patients over 70 years beginning dialysis with a CRP value <3 mg/L had a higher cardiovascular risk than those with a CRP value >3 mg/L. Multivariate analysis showed that the independent risk factors for cardiovascular events were, in the whole cohort, age over 70 years, previous cardiovascular comorbidity, and interaction between age and CRP. Conclusions: This trial shows a reverse relation between cardiovascular risk in dialysis patients over 70 and CRP level. This may be a useful element in evaluating older patients before long-term dialysis. [ABSTRACT FROM AUTHOR] |
